OIL-BURNER.

SPECIFICATION forming part of Letters Patent No. 501,692, dated July 18, 1893.

Application ned December 19, 1892.

To all whom it may concern:

13e it known that I, WILLIAM T. PUTNAM, a citizen of the United States, residing at Brightwood, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Oil-Burners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in theY art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked and more particularly pointed out in the claims, reference being had to the accompanying drawings, in which- Figure 1 is a view partly in elevation and partly in section of 'a stove with one of my burners therein connected with an oil supply. Fig. 2 is an enlarged central section through the burner, its shell, deector and central draft pipe. Fig. 3 is a top plan view of the burner resting in place on the lower part of the shell, with the delector removed. Fig. 4 is a plan view of the burner with its lling removed. Fig. 5 is a cross section through the central air iue of the burner on the line Fig. 2.

In detail, 1 represents a stove of any ordinary form or construction 2 the fire-pot, and 3 the grate of the same, l

4 is the burner proper, which is circular in form, and has an openV center with flanges around its outer and inner edges, the burner having arms Vor lugs 6 formed on its outside which are supported in brackets 7 formed on the inside of the lower part S of the burner shell. In the center of the burner is formed a hollow head 9 which is connected to the burner by short hollow arms 10 which serve as oil inlets to the burner, a pipe 11 being tapped into the head 9 from below, and eX- tends to the outside of the stove, where it is connected with an oil tank 12, valves 13 being connected to such pipe for regulating the liow of oil. Around the oil supply pipe 11, from a point just below the burner to apoint Serial No. 455,659. (No model.)`

outside ot' the stove, is secured a pipe or casting 14, this pipe being of a greater diameter than the supply pipe 11, and serves the purpose of a central air draft to the burner and also to keep the oil cool until it is practically in the burner, the pipe 14 being held around the supply pipe 1l by means of set screws 15 shown in Figs 2 and 5. On the top of the headl) is a threaded projection 16, and on this is'adapted to be screwed an air deilecting cone 1'7V whose top is alittle above the upper edge of the burner, thus directing the central air draft, which is secured mainly through the pipe 14 over the top of the burner. The

s'sv

air deiiector 17 has also a projection on its l top over which fits the base ot' the flame deflector 18.

The burner 4 has preferablyalling of mineral substance, such as sand, and the upper part of theburner shell has an open contract.- ed top which-is about on a line with the up; per edge of the burner, and acts to deiiect the outer air current which cornes through the ordinary draft opening of the stove, over the top of the burner and on an angle opposite of the inner air current. The part 19 of the shell being screwed on to the lower part 8 may thus be adj usted to direct the outer air Acurrent at the desired angle.

In operation, the oil being turned on, it passes through the pipe 11, head 9, and short arms 10, and lters up through the burner lling, when it may be lighted. The air current through the pipe or casting 14 keeps the oil perfectly cool until it reaches the burner, when it is suddenly heated, and may be said to generate into a gas, which, after the burner is well heated, is lighted into a tiame atk about the point where the inner and outer air currents meet over the top of the burner. These two currents working against each other mix perfectly with the oil products, and perfect combustion is secured. The llame being deilected above into a larger area by the dellector 1S, the dellecting cone 19 being screwed on the top of thehead 9, and the upper part of the shell 19 screwed on the lower part 8, both may be adjusted to direct the inner and outerair drafts at the angle of meeting that the best results may be obtained.

Modifications may be made in my device to adapt it for use in other stoves,or to simplify the construction, but the principle and operation will remain the same.

What I claim as my invention, and desire to secure by Letters Patent, is the following:

l. In an oil burner having an open center, a pipe with open ends, one below the center of such burner, and the other extending to the outside of. the stove, whereby a central. air draft is furnished the burner, substantially as set forth.

2. In an oil burner having an open center and connected with an oil supply pipe by hollow radial arms, a larger pipe with open ends surrounding such supply pipe from a point below the burner to the outside ofthe stove,y thereby giving a central air draft to such burner and keeping the supply pipe cool, substantially as shown and described.

3. An oil burner consisting of a circular pan with a lling of suitable material and adapted to be connectedwith an oil supply through a central pipe, such pipe inclosed in la larger one from a point below the burner to theoutside of the stove, and a central air deflec-v tor supported above such inclosing pipe for spreading the air supply through such pipev above the burner, substantially asset "forth,

4. An oil burner having'an open center and connected with an oil supply, such Vburner supported centrally within a surroundingf shell or air flue, such shell having an adjust' able extension on its top with contracted edges, whereby the space between the 'edgesl of the extension and the burner may be ad j usted substantially as set forth.

5. An oil burner havingan open center and connected with an oil supply, such burner supported centrally Within a surrounding shell or airline, such shell having an adjustable extension on its top with contracted edges whereby the space between the edges of the extension and the burner may be adj usted, an air defiector adj ustably supported within the open center of the burner and a llame detlector above, substantially as set forth.

6. An oil burnerhaving an open center and connected with an oil supply, such burner centrally supported Within a surrounding shell or ilue, an extension screwing on such shell, the top of such lextension being con' trac-ted, an air dei-lector adj'ustably supported within the open center of theburner, a 'flame deflector above, and an air pipe leading from without the stove to a point just below the `central air detlector, all 4substantiallyas set forth.

7. An oil burnerhaving an open center and supported within a'surrounding'shell, ahead in such open center connected with an oilsupply, and with the burner by radial pipes, a deector adj ustably supported on said head,

'and a flame detlec'tor above such air detlec'tor,

all substantially as set forth.

1n testimony whereof I affix mysignature in vpresence of two witnesses.
